is it possible to clone stormtroopers with resin/plastic? is it cost feasible?

I personally haven't casted any stormtroopers however The Scoundrel has done so with some nice results. As far as the cost goes there are some kits available for reasonable cost. I usually cast heads & hands & then use pre-existing bodies from other figures & sculpey to do my work. I have used smooth on casting products and have gotten great results (haven't done it in awhile thought).
